USAir has a Motorola Type II 900 MHz trunked system at Sky Harbor. It's fairly active.
I listened to some of the talkgroups that popped up frequently:
16Emergency TG
3520Ground ops. Possibly related to cargo. Heard the same people on 463.3875 D315. Reading weights in the several thousands.
3360Bag runners?
5920Calling ticket counter. BSO answered. Someone was at extension 5929.
48000Some ramp ops. Two calls to baggage. Something related to a pair of seats on board an aircraft. Load controller was heard here.
Despite me telling Trunk88 that this is a 900 MHz system, it still thinks it's an 800. CTL and log files attached for reference.
